Glazing system

ABSTRACT

A glazing system for large glass windows wherein the opening is framed by a narrow surface coplanar with the opening and an outer surface perpendicular to the plane of the opening. The perpendicular surface has a channel therein spaced from the coplanar surface into which a portion of a resilient stop is forced. The stop has an outer portion including a window engaging lip and a perpendicular surface engaging lip, the arrangement being such that the outer portion is rotated toward and into pressure engagement with the glass by the engagement of the perpendicular engaging lip with its surface as the stop is forced into the channel. A tacky semi-compressible sealant placed between the glass and the coplanar surfaces is thus placed under compression. Shims prevent over compression. The stop engages the bottom of the channel when fully inserted so as to be accurately located and provided a straight sight line.

has been, and continues tobe, a popular architectural concept. Buildingswith concrete walls are to be found not only in high rise officebuildings but also in low cost individual housing. However, somedifficulty has always been experienced in providing for the installationof windows in such concrete walls. For example, it is not unusual toexperience chipping or spalling of the concrete around the windowopenings. Moreover,

.voids or protrusions in the concretein the areas of the openingsfrequently occur thereby making it difficult to install and seal a panelin the opening. Still further, it is both difficult and more expensiveto employ forming techniques which assure the attainment of uniformdimensions around the window opening in a concrete wall.

Prior art glazingsystems have normally employed some form of astop orabutment which, in combination with conventional shims, setting blocks,wedges and sealants, function to seal and hold the glass in the wallopening. Typically, the stop or abutment is some form of a metal framewhich is removable so that the glass panel may be inserted in the wallopening and thereafter secured to the sash or sill to maintain thesealant in engagement with the surface of the glass. As can beappreciated, removal of the glass first requires the removal of the stopmember. In addition, the stop member itself comprises a substantial itemof cost and also normally involves substantial labor costs for itsinstallation. Still further, the stops normally are of a fabricatedmetallic design and, consequently, the configuration of the stop isrestricted to the available forming techniques. This limitation in turnacts as a limitation on the configuration of windows which may bedesigned.

The present invention contemplates a new and improved glazing systemwhich overcomes all of the above referred to difficulties and others andprovides a window glazing system which involves a minimum number ofpieces in order to provide an effective window seal which is both simpleand economical to manufacture and install.

In accordance with the present invention, the surfaces defining theopening include a first narrow surface coplanar with the opening, asecond surface disposed outwardly from the center of the opening whichisgenerally perpendicular to the plane of the opening,

and a channel spaced from the first surface facing the center of theopening. A tacky and partially flowable sealant material is then placedon the coplanar surface and the panel which is to fill the opening ispressed thereagainst. An elastomeric stop member is provided having achannel insertion portion and a wider sealing portion which remainsoutside of the channel, the arrangement being such that when the channelinsertion portion is inserted in the channel, a first surface on thesealing portion engages the generally perpendicular surface and rotatesor moves a second surface on the sealing portion into pressureengagement with the panel to place the sealant under a constant, butuniform and steady, pressure. Shims are provided to prevent the sealantfrom compressing excessively. The length of the channel insertingportion is preferably such that it bottoms in the channel so that thesight line of the stop will be positively located and straight relativeto the periphery of the window. The channel insertion portion isprovided with laterally extending fins which flex and collapse so as topermit ready insertion of the insertion portion into the channel butexpand on removal soas to prevent ready removable therefrom.

The sealant ispreferrably of a material which does not dry or harden orset throughout the expected life of the installation. Also, itpreferrably has tacky surface characteristics such that when compressedbetween two surfaces, it will adhere tenanciously thereto so as toprovide a water and air tight seal between the coplanar surface and thesurface of the panel. The material of the sealant is in tape or stripform and is preferably a semiplastic having flow characteristics whichprevent it from flowing under the force of gravity when in position in avertical or an upside down horizontal position, but yet will flow to alimited extent under pressures exerted thereon by the elasticity of thestop member pressing against the other surface of the panel.

The stop member is preferrably of an elastomeric extruded material suchas neoprene which, when flexed from its normal unstressedshape, willcontinue to exert pressures on its restraining surfaces attempting toreturn to its unstressed state.

The surfaces defining the opening may be the concrete itself as in thepoured and hardened condition, but in accordance with a more limitedaspect aspect of the invention, the glazing system contemplates aspecially designed reglet adaptedto be cast directly into the concretewall so that at the reglet defines the window opening. Thus, the regletincludes a first surface adapted to be generally perpendicular to theplane of the opening, a sealing surface adapted to be coplanar with theplane of the opening, and a second surface adapted to be perpendicularto the plane of the opening and outwardly therefrom which includes achannel therein spaced from the sealing surface.

The principal object of the invention is the provision of a new andimproved glazing system for sealing windows in concrete walls whichovercomes all of the difficulties of the prior art and which is simplein constructing economical to manufacture and readily installed.

Another object of the invention is the provision of a new and improvedglazing system wherein an elastomeric stop member is so arranged withits supporting surfaces that it is moved into pressure engagement withthe glass as it is installed.

Another object of the invention is the provision of a new and improvedglazing system wherein the stop member bottoms in a channel whichsurrounds the opening so as to align the outer surfaces of the stopmember to maintain them in a straight position relative to theperipheries of the window opening.

Another object of the invention is the provision of a new and improvedglazing system for windows and concrete walls wherein a semi-plastictacky sealant may be used for the purpose of sealing the window in placewhich sealant will always be under a generally constant and uniformpressure.

I Another object of the invention is the provision of a new and improvedglazing system which is comprised of only four components; namely, areglet, a sealant, a shim and an elastomeric stop member.

The glazing system is equally adapted for use in walls other thanconcrete. For example, the system may be adapted to metal framing orwood framing or it may be used with material such as limestone or thelike.

Referring now to the drawings, FIG. I shows a panel P installed in aconcrete body 10 by the glazing system which comprises the instantinvention. Thus, a reglet l2 surrounds the entire opening and ispreferably placed around it during the casting process. This reglet ismost desirably of an extruded rigid PVC material. In the embodimentshown in FIG. 1, reglet 12 includes a channel portion or groove 14 andlaterally extending shoulder portions 16, 18 on opposite sides of andcoextensive with the channel. The channel is defined by opposite sidewalls 20,22 and bottom wall 24. Side walls 20, 22 have exteriorprojections 26 at spaced elevations therealong which serve to retain thereglet in concrete body 10. The interior surfaces of walls 20, 22include inwardly extending projections 28 which cooperate with a newresilient stop 30 which is adapted to be received in channel 14 for apurpose which will hereinafter be described.

Shoulder 18 includes a substantially flat planar upper surface 32 whichis generally perpendicular to the plane of the opening and panel P. Asimilar surface 34 is provided on a portion of shoulder 16, surface 34comprising a ledge on which panel P is to be received.

Extending vertically upward from ledge 34 is flange 36 which has asubstantially vertical side surface 38 which is coplanar with panel Pand spaced from surface 32. Four of the above described reglets,abutting at their ends, cooperate with concrete body 10 to provide auniform frame or support having continuous surfaces and a continuouschannel around the opening. Since the dimensional tolerance of reglet 12may be controlled during the extrusion process, it is possible toachieve a uniform dimension of the reglet in order to minimize theeffect of dimensional variations occurring from the process by whichconcrete body 10 is formed.

Cooperating with reglet 12 to complete the glazing system is acombination of four separate elements. The first of these is sealantstrip 40 positioned between panel P and coplanar surface 38. Since it ison the outside, this sealant comprises the principal weather seal. Inthe preferred form of the invention, the material of strip 40 is apreformed extruded sealant tape which is of a semicured, tacky natureand which is available commercially as a preformed, semi-cured,architectural grade butyl tape. The material is a semiplastic capable offlowing under pressures greater than that imposed by gravity and has asurface having pressure sensitive adhesive characteristics, such thatwhen panel P is pressed thereagainst, the material adheres to the paneland to reglet 12.

The second element of the combination which cooperates with reglet 12 issetting block 42 which, in the form illustrated in FIG. 1, rests on theledge 34. The setting block is preferably constructed from a neoprenematerial.

The third element of the glazing system combination is spacer shim 43which is also located on ledge 34. The spacer shim is preferably ofneoprene and limits the amount of compression of sealant strip 40.

Setting block 42 and shim 43 may be made integral if desired. Also, theymay be continuous around the window but preferably are a plurality ofshort spaced segments.

The fourth element is the new resilient stop 30. Stop 30 is formed of anelastomeric material such as extruded and cured neoprene and iscomprised of (FIG. 7), a body portion 44 and a depending stem portion 46connected by a neck portion 45to the body portion. Projecting fromeither side of stem portion 46, are longitudinally extending ribs 48.These ribs extend outwardly and upwardly away from the lower end of stemportion 46 and coact with ribs 26 to permit easy insertion of the stemportion into channel 14, but difficult removal. Body portion 44 furtherincludes an outer wing portion 49 having an abutment surface 50 whichslopes downward and away relative to the longitudinal axis XX (FIG. 7)of stop 30 and terminates in a sealing lip 51. The body portion furtherincludes a surface 52 which upwardly diverges from the plane of stemportion 46 to form a sealing lip 53 at its upper edge.

The length of stem 46 is such that when the lower end of stem 46 is infirm engagement with the bottom of groove or channel 14, lips 51 and 53are in engagement with surface 32 and panel P and are deformedelastically a substantial amount so as to form a pressure seal. Lips 51and 53 are so dimensioned that they contact their cooperating surfacesbefore stem 46 bottoms in the channel. Thus as stem 46 moves intochannel 14, lip 51 contacts surface 32 and begins to deform elasticallyinto a contact surface and at the same time, the deforming force turnsbody portion 44 counterclockwise as seen in FIG. 1 about a longitudinalaxis in position 45. As body portion 44 turns, lip 53 is biased towardpanel P so as to be in firm uniform pressure engagement therewith alongits entire length. As stop 30 is pushed yet further into the channel,the contact areas leftward of lip 51 and below lip 53 increase untilstem 46 bottoms and effectively resists further downward movement ofstop 30. Reglet 12 is sufficiently straight throughout its length that,with stop 30 firmly bottomed in the channel throughout that length, theline of intersection of lip 53 with panel P will be substantiallystraight. When panel P is glass, or is a color which contrasts sharplywith the black of stop 30, it is desirable that the line of intersectionbe straight, because it is the sight line, or line which catches theobservers eye as he looks at the panel. I

Ribs 48 project toward the opening of the channel and thus exert acontinuing pressure or bias on stop 30 directing it towards the bottomof the channel thereby helping to maintain the sealing pressuresdiscussed above. The ribs are further aided in the action by thecooperation of projections'28 in the sidewalls of the channel.

The foregoing combination of elements cooperates to mount and seal apanel in a concrete body 10, including reglet 12, in the followingmanner. The preformed sealant tape, 40 is applied to vertical wall 38 ofthe reglet. Shim 43 and setting block 42 are placed on ledge 34. Panel Pis then positioned on setting block 42 with shim 43 between the paneland surface 38. Thereafter, the panel is pressed against sealant tape40. Resilient stop 30 is then inserted into channel 14 and forced downinto the channel such that the lip 53 engages the surface of the panel,exerts a resilient pressure against the side of panel P and compressesthe panel against sealant 40. Shim 43 serves to limit movement of panelP against the sealant to thereby avoid any excessive compression forcewhich would tend to squeeze the sealant completely out of the groove.With stop 30 in the position illustrated in FIG. 1, abutment surface 50is in firm engagement with flat planar surface 32 on reglet l2, andbecause of the opposing turning bias of lips 51, 53, both lips havedeformed into contact areas. Moreover, because of the resilient natureof stop 30, there is a continuing pressure exerted against panel P tomaintain it in sealing engagement with sealant 40, and the surfacecontact of stop 30 below lip 53 and the face of panel P serves as a sealfor the inside portion of the panel. It will be readily apparent that itis a relatively simple matter to remove stop 30 for replacement of thepanel. However, the tacky characteristics of sealant 40 are such thatthe sealant will be destroyed by removal of the panel. It then becomesexpedient to remove the remaining sealant from surface 38, shim 43, andwherever else it may be and replace it. The glazier then resets panel Pand reinserts stop 30 in the reglet to re-establish the necessarysealing pressure on the panel. Ribs 48 and projections 28 exert asubstantial desireable holding force on stop 30 which may be overcome toremove the stop and which offer only neglible resistance to reassemblyof the parts.

The same basic glazing system may be employed with materials other thancast concrete. For example, there is illustrated in FIG. 2 a cutlimestone body 60 in which the reglet has been eliminated but whereinits function has been retained by cutting into the limestone a channel61, a support ledge 62 and a vertical surface 63. Resilient stop30',setting block 42 and sealant 40 may be the same as that described inconnection with the embodiment shown in FIG. 1. In the embodiment shownin FIG. 2, stop 30' also has a stem 46"long enough so as to bottom inchannel 61. The several elements cooperateto mount and seal the panel tothe limestone body in substantially the same way as shown in FIG. 1.

FIG. 3 illustrates use of the gasketing system in the installation of apair of glass window panels in an opening in a concrete wall. Windowpanels 74,75 may be of a conventional insulating construction, eachcomprising a pair of glass panels 65, 66 (FIGS. 4, 5 and 6) sepa ratedby a spacer 67 at the top and bottom thereof. A protective metal band 68is received over the top and bottom edges of panels 65, 66.

As in the embodiment of FIG. 1, a reglet 12' is cast into the concreteas the concrete wall is formed so that the reglet defines the frame inwhich the glass panels are received. Reglet 12' includes 34', 38disposed as surfaces 34, 38 of reglet 12 and as hereinbefore discussedrelative to FIG. 1. In addition to the reglet, a center mullion member70, which may be an aluminum extrusion, extends across the opening andis secured to the side walls thereof. Mullion member 70 is bestillustrated in FIG. 4 and, as is apparent from its cross sectionalconfiguration, provides an upper and lower framing configuration whichis substantially the same as that provided by reglet 12'. Thus, theupper surface of member 70 includes a channel or groove 71, a supportledge 72 and a vertical surface 73. The lower surface of member 70 is amirror image of the upper surface.

When lower glass panel'74 is installed as best shown in FIGS. 4 and 6, asetting block 76 is positioned on ledge 34' of reglet 12'. The settingblock 76 differs from setting block 42 of the embodiment of FIG. 1 inthat it is L-shaped in a cross sectional configuration and includes asupport leg 77 and a vertically extending leg 78 which functions as aspacer shim. Similarly, a setting block 76 is also received along ledge72 of mullion member 70. As in the embodiment of FIG. 1, the sealant 40'is applied to the surface38' of the reglet. As will be appreciated, thesealant extends around the entire periphery of the opening in whichpanel 74 is to be received, including the vertical surface 73 on themullion member 70. As before, sealant 40 may be in tape form.

Glass panel 74 is positioned on setting blocks 76 and pressed againstsealant 40'. Leg 78 of the setting block serves as a stop member toprevent the squeezing out of the sealant in the same manner as shim 43of the FIG. 1 embodiment. With the window panel in position in theopening, resilient stops 30" are inserted in reglet channel 14' andchannel 71 to resiliently urge the panel into sealing engagement withsealant 40'.

The upper window panel is installed in the upper opening in preciselythe same manner as the lower window panel 74 and a further descriptionof that installation is believed to be unnecessary. It willbeappreciated that additional windows may be installed in like resentareas or reduced thickness which are sufficiently strong to remainconnected during normal handling of the setting block but which, ifdesired, may be broken off in order that leg 77" may be shortened so asto accommodate different thicknesses of panels or window panes.

Several advantages of the disclosed glazing system should be noted. Aspointed out above, this system makes it possible to install panels withfacility even though the system is used with a rough cast material inwhich dimensional control may be less than accurately maintained. Thestop when bottomed in the groove has its outer surface or sight lineautomatically held straight without any skill required by the installer.Moreover, the same basic system is readily adaptable to openings ofvarious sizes, it being necessary only to vary the length of eachelement in the system to accommodate for different sizes. Further, thesystem is one thatcan be readily installed and can be readilydisassembled for replacement of a panel. Still further, the systemachieves a substantially uniform sealing pressure around the entireperiphery of the panel and there is nothing in the system to shrink, dryout, rust or otherwise deteriorate. The system may be employed with awide diversity of materials to thereby make it possible to use the samebasic system on a wide diversity of structures. Finally, and mostimportantly, the new resilient stop is more effective than the stopmembers employed in previous systems. As a result, the same basic systemmay be employed on a wide diversity of shapes and sizes of windows, itbeing necessary merely to bend the stop to conform to the specific shaperather than forming a special stop for each window.
